If you look in your home directory there is probably a sound-file  
called test.aif (or just search for test.aif in the spotlight) to  
which csound has written its output. For a real-time performance you  
need to specify output to dac in the flag-line, so try this:

csound -odac test.csd

where -o (NOT zero) stands for output and dac for the default digital  
to analogue convertor (i.e. the default output soundcard of your  
system). You get all the options if you just type csound in the  
terminal. Or check out this page:

file:///Library/Frameworks/CsoundLib.framework/Resources/Manual/CommandFlagsCategory.html

For better performance you may also need to tune the hardware and  
software buffer sizes with the flags -B and -b. Try starting with  
something like:

csound -odac -b1024 -B1024 test.csd

Note that the size is usually a power of 2 (256, 512, 1024 etc).

Thanks, got it to work with the -odac line in the terminal. Had a bit
of a blank moment there. But it is all making sense now. Thanks for
the link. Will go check that out so get a better understanding og the
flags.
